Please note: if your site is listed with Google already, then any further attempt in submission would not help expedite listing. When you search ‘Google submit’ you can find the page where sites are submitted. Obviously, their page would be the first one to appear, but there are other faster ways to get your site noticed by them.
One good way to get your site indexed quickly by Google is through links from websites that are themselves crawled regularly. Perhaps the quickest and the most successful way is to use the advantages of online directories. Google has the habit of scrutinizing top level directories regularly and when any site has links from these the site also gets noticed quicker.
You can choose between free and paid subscription directories depending on the kind of budget you have as well as your suitability. The best type to choose are the business directories which deal with your line of business since Google looks for commonality while indexing your site. Your site should be highly relevant to a business directory for your line of business.
DMOZ, also known as the Open Directory, is probably one of the most important directories to get listed in if you are interested in good rankings from Google. This is not the way in which you can accelerate the speed which Google takes to notice you. Several weeks or months can pass before you get listed by DMOZ. The reason for this is that every site is checked by a category editor personally and your site could be down below in the queue. One critical issue here is that when submitting to DMOZ, remember to read and comply with each and every guideline they have and provide all that they ask for.
Another proven way to get noticed by Google is to submit articles to sites which take articles. Most of the reputed article submission sites permit you to insert a box called ‘About the Author’ or ‘Author Resource’. This is the place which is meant to carry the critical link to your site.
If the articles are good, then your articles could also be chosen by other sites for inclusion and this is another advantage of writing articles. It is to be understood though that they must carry the Author details section at all times and this gives you a free link to your site. This is yet another chance for Google indexing your site and if the topic of the article is in line with your business then chances are that you would get increased visitors to your site as well. To sum it up, while you have the option of direct submission to Google, you could also try directories or article writing, which could bring quicker results.
